OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 386,054, dated July 10, 1888.

Original application filed March 15, 1887, Serial No. 230,985. Divided and this application filed November 26, ISST. Serial NoA To @ZZ whom, it may concern,.-

Be it known that I, GEORGE A. BEACH, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvementin Carriage Speaking-Tubes,of which the following is a specification.

My invention relates to carriage speakingtubes, and more particularly to improvements upon the carriage speaking tube heretofore patented to mein Letters Patent ofthe United States, No. 363,979.

The obj ect of my present invention is to provide a carriage speaking-tube extending from the seat of the carriage to the drivers seat thereof, which maybe contracted or telescoped out of the way, leaving no projecting part liable to injury or to afiect the neat appearance of the carriage, and wherein the mouth-pieces are provided with whistles and hinged caps.

To this end my invention consists, in connection with the carriage, the telescoping or contractible speaking tube and its mouthpieces, of a hinged cap or covering-disk furnished with a double-disk whistle, being integral with the hinged cap, so that no part of the whistle will project beyond the mouthpiece or its hinged cover.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a sectional view of a carriage, showing my invention in elevation. Fig. 2 is an enlarged longitudinal vertical section of the speakingtube. Fig. 3 is an enlarged sectional view of the mouth-piece and whistle. Fig. 4 is a detail perspective view of the mouthpieceholding clamp.

In said drawings, A represents a carriagebody; A', the carriage-seat; A2, the drivers seat, and A3 represents the door of the carringe.

B is the stationary or non-sliding tube or part of the speaking-tube, extending from the front ofthe carriage-body, or the vicinity of thc drivers seat, under the top or roof of the carriage. This tube B should be made of two or three ply rubber hose, and is, or may be, supported by the upholstering a, which thus serves to conceal the tube from view as well as to support it.

The drivers end of the (No model.)

tube is secured and firmly supported by a metallic socket or thimble, b', secured in a suitH able hole, I), in the frame-work A" of the cai riage-body. The socket has a flange, b2, which is countersunk in the frame. The thimble b is shaped to receive the mouth-piece C and constitutes the socket in which the mouthpiece ts, and by which it is concealed from view and protected from injury. rIhe socketu piece b is provided with screw-threads b3 on its sleeve portion bt, by which it may be secured in the frame Ai. These screw-threads also serve to firmly unite the stationary tube B to the sleeve of the thimble. A suitable cement, however, should be applied before the sleeve b4 is inserted in the rubber-hose tube B.

The mouth-piece C is secured to a sliding or telescoping section or part,D,of the speakingtube,which is preferably made of flexible hose, stiff. enough, however, to be readily pushed back into the tube B after it has been drawn out. This tube D is of somewhat smaller diameter than the tube B, and is provided with a shoulder or button enlargement, d, at its inner end, so that the friction thereof on the tube B will serve to retain the sliding tube D in its retracted position.

The mouth-piece C is of a daring conicalor bell shape, and is furnished with a short nearlycylindrical rim or shoulder, c, having an inturned Harige or fold, c', thus forming a smooth rounded edge for the mouth-piece,and`

also a seat or head for the ange f of the hinged cover F to iit or clasp over, and thus hold the hinged cover securely closed. The rim or shoulder cis in fact made somewhat flaring, as indicated clearly in Fig. 3, the outer edge of the shoulder being rounded by the fold c, so that this rounded daring shoulder has a kind of wedging action on the flange f of the hinged cover, and springs the same outward as the cover is being closed. The cover F is furnished with a hinge, j", connected by a bracket or strap, f2, to the mouthpiece C. The hinged cover F is furnished with a double-disk perforated whistle. One disk of the whistle consists of the cover-disk F itself, which is furnished with a raised center, f, having a whistle hole or perforation, ft, therein. The innerdislcf, of the whistle is soldered upon the inside of the cover-disk F, and is furnished with a whistle holc or perforation, f, opposite the holef" in the disk F, but of smaller diameter.

The inner or small 'end of the mouth-piece C is furnished with a short metallic tube or sleeve, C', soldered thereto, which is adapted to lit within the rubber hose or tube D, and also with an outer thimble or sleeve, C?, of a larger diameter, which is adapted to t over the hose-tube D. The two sleeves Cf andC" thus form between them an annular chamber the thickness of the hose D, for the purpose of receiving and securing the mouth-piece to the hose D. By simply pushing or inserting the end of the hose into this annular chamber, a little cement of any suitable kind being first applied, the mouth-piece may be very securel y, as well as easily, attached to the hose.

The stationary tube B is provided with a metallic elbow, E, at its inner end, to which a stationary tube, G, is attached,which extends down from the top of the carriage at the side thereof to the carriage-seat A. The section G is preferably made of rubber hose, and may be attached to the elbow .E in any suitable manner. It is provided at its lower end with a mouth-piece, 0*,which is or may be in all respects similar to the mouth-piece C before described, and is provided with a similar hinged cover and whistle. The tube G is further furnished near its lower end with a collapsible rubber bulb, g, by which the whistle of the drivers mouth-piece may be operated when desired. The tube G extends down the side of the carriage, preferably in about the position indicated in the drawings, and is held in place by a wire spring-clamp, H, secured to the frame of the carriage by a hinge, h. The middle portion, h', of the clamp is thepivot of the hinge. The clamp has two vertical arms, h2 h2, extending down from the pivot 7L', and two horizontal arms, hgh, inclined toward each other. The arms It h3 stand in a horizontal plane, or about at right angles to the vertical arms h2 h2. The horizontal arms h3 h3 are connected to the vertical arms h2 h2 by springcoils rl, which are adapted to permit the clamp-arms h3 hi to spring or open outward from each other in a horizontal plane,and also to spring up or down in a vertical plane. By reason of this double-spring movement of the clamp-arms h3 h3 the mouth-piece C* may be removed or disengaged from its holding-clamp readily,whether it be pulled directly outward or up or down. The ends of the clamp-arms h3 h3 are furnished with curved ends or coils h5 h5.

This application is iiled as a division of my application Serial No. 230,935, filed March 15, 1887, and I do not herein claim the subjectmatter claimed in said application Serial No. 230,935.
